The cormorants sat quietly as we walked by this small pier. The collection of birds and sign caused Karl to stop and take this photograph. Never let an opportunity like this pass by.
A little later we returned along the same trail, and heard one of the birds on the small pier making loud, constant calls. Usually described as gutteral, I saw one reference comparing it to the oinking of a pig. That bird definitely targeted the calling to one of the others on the pier, first directly at it and then winding its neck around continuing to call. As we watched, the other bird joined the caller, and the pair remained together as we continued our hike.
